WebbSome of these cells will differentiate into capillaries, while others will become osteogenic cells and then osteoblasts. ... The osteoblasts secrete osteoid, uncalcified matrix, which calcifies (hardens) within a few days as mineral salts are deposited on it, thereby entrapping the osteoblasts within. Once entrapped, ... Webb26 sep. 2024 · Capillaries and osteoblasts from the diaphysis penetrate this zone, and the osteoblasts secrete bone tissue on the remaining calcified cartilage. Thus, the zone of calcified matrix connects the epiphyseal plate to the diaphysis. A bone grows in length when osseous tissue is added to the diaphysis.

WebbAnswer and Explanation: 1. Cells that secrete the organic components of the bone matrix are called osteoblasts. These cells are derived from osteoprogenitor cells. These are cuboidal or polygonal mononuclear cell lining the bone surface and closing cone of resorption canals. Webb8 juni 2024 · Bone consists of four types of cells: osteoblasts, osteoclasts, osteocytes, and osteoprogenitor (or osteogenic) cells. Each cell type has a unique function and is found in different locations in bones. The osteoblast, the bone cell responsible for forming new bone, is found in the growing portions of bone, including the periosteum and endosteum.

WebbMesenchymal cells differentiate into osteoblasts which secrete osteoid. Once the osteoid becomes mineralized (calcium is deposited within it) the matrix becomes bone and the trapped osteoblast becomes an osteocyte. What type of bones are generally formed by this method?
